Identify this action as either a physical or chemical change. Ice melting.
Ice melting is a physical change. During this process, ice transitions from a solid to a liquid state (water) without changing its chemical composition.
Identify this action as either a physical or chemical change. Rotting banana.
Rotting a banana is a chemical change. During this process, the banana undergoes decomposition, resulting in the formation of new substances and changes in its chemical structure.
Use the picture to determine if a chemical reaction has occurred.
I’m unable to view images, but I can help you identify signs of a chemical reaction based on descriptions. Look for indicators such as:
- Color Change: Has the color of the substances changed?
- Temperature Change: Did the reaction produce heat (exothermic) or absorb heat (endothermic)?
- Gas Production: Is there any bubbling or gas formation?
- Precipitate Formation: Has a solid formed in a liquid solution?
- Irreversibility: Is it difficult or impossible to reverse the process?
If you can describe the image or the scenario, I can help you determine whether a chemical reaction has occurred!
